This invention relates to a clamp, especially designed for use inconnection with construction work, and aims to provide novel meanswhereby uprights or cross bars of scaffolds, or

other building apparatus may be securely clamped together in theformation of portable supports or scafiolds.

An important object of the invention is to provide a clamp of thischaracter embodying a wedge shaped member adapted to be forced between amovable end bar of the clamp, and an article being clamped by thedevice, so that the clamp may be positioned without the use of nails,screws, or other securing means.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in. the

29 details of construction hereinafter described and claimed, it beingunderstood that changes in the precise embodiment of the inventionherein disclosed, may be made within the scope of what is claimed,without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a view illustrating bars of construction work securedtogether by means of a clamp constructed in accordance with theinvention.

Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a view of the clamp ready to be positioned.

Referring to the drawing in detail, the

clamp embodies end members 5 and 6 respectively, the end member 6 beingprovided with teeth 7 to bite into the bars or bar to which the deviceis secured, to insure against the bars 9.

Serial No. 323,365.

in a manner as shown by Figure 3, where upon the bars to be connectedare placed side by side as shown by Figure 1. The clamp is nowpositioned in such a way'as to grip the overlapping ends of the bars tobe connected and the bar 5 is moved to a position between The wedge 12is now driven into position behind the bar 5, with the result that thebars being connected, and which are indicated. by the referencecharacter A, are forced into close engagement with each other andsecurely held in such a way that the use of nails and screws isunnecessary.

Should it be desired to release the clamp, the wedge may be struck fromthe pointed end moving the wedge in the opposite direction permittingthe clamp to open.

I claim:

1. A clamp of the class described including an end bar, pairs of sidebars pivotally connected with the end bar and arranged on opposite sidesthereof, a pivoted end bar mounted between the pair of side bars at oneside of the clamp, a pin for connecting the opposite pair of side barsat the free ends thereof, said pivoted end bar adapted to pass under thepin, and a wedge shaped member slidably mounted between the secondmenpair, latching means for latching the free end-of the last mentionedbar, and a Wedge contacting with the swinging bar and artioles beingconnected by the clamp to hold the swinging end member against movement.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature. n

AUBREY DELOS TURNER.
